The TEKTRONIX 2465 Oscilloscope
is a portable 300-MHz instrument having a four channel vertical deflection
system. Channel 1 and Channel 2 provide calibrated deflection factors from
2mV per division to 5V per division. For each of these channels, input
impedance is selectable between two values: either 1M Ohm in parallel with
15pF, or 50 Ohm internal termination. Input signal coupling with 1M Ohm
impedance can be selected as either AC or DC. Channel 3 and Channel 4 have
deflection factors of either 0.1 V or 0.5 V per division. Each of these
channels has an input impedance of 1M Ohm in parallel with 15 pF, with
DC input signal coupling. Trigger circuits enable stable triggering over
the full bandwidth of the vertical system.
The horizontal deflection system provides calibrated sweep speeds from
1.5 sec per division to 500 psec per division. Drive for the horizontal
deflection system is obtained from a choice of A, B delayed, A alternated
with B delayed sweeps, or CH 1 (for the X-Y display mode).
The 2465 incorporates alphanumeric crt readouts of the vertical and
horizontal scale factors, the trigger levels, time difference measurement
values, voltage difference measurement values, and certain auxiliary information.
